This line gives me a "cannot find symbol variable request" String userID = request.getParameter("userID");
This line gives me a "cannot find symbol variable request"
String userID = request.getSession().getAttribute("userID");
This line gives me a "cannot find symbol variable request" HttpSession session = request.getSession(); String userID = session.getAttribute("userID");
This is not a servlet so request is not available. There has to be a way for non-servlet classes in a web app to access the session object? Correct?

String userID = request.getSession().getAttribute("userID");
or
HttpSession session = request.getSession(); String userID = session.getAttribute("userID");
However, really, as you have been told twice, what you want is:
String userID = request.getParameter("userID");
RIght?
